okay so I have to work out this problem for school work and I don't understand it. the problem is : if the perimeter of an isosceles triangle is 2x + 10, what is the length of one of the congruent sides ?

• math -

well, if sides are both x and the base is 10 then the perimeter is 2 x + 10
so the sides are x, period, no more can be said.
If it were equilateral, then every side would be 10
